You can add Belgium, Holland and Italy to that list, they were all variants of a Robert Stevenson designed loco called (appropriately) “Patentee”. Despite being built in numbers (many under license) no originals appear to have survived, I suspect this is due to major structural items such as the frames being made of wood (although these were clad in metal, see @Uncle-Heavy’s photo): https://forums.kitmaker.net/uploads/default/original/4X/0/1/8/018a4a9db1c82f8fd0b2feac64075895013cf732.jpeg
The wooden construction imparted some flexibility to the structure, an advantage with the flimsy and irregular early railway lines they had to run on.
You’re going to love this old lady; Furness Railway No.3 “Old Coppernob”, she lasted in service so long (about six decades) that when she ended her working life in the first year of the 20th century her heritage value was recognised and she was placed in an iron-framed glass structure on the platform of Barrow-in-Furness station.
